My invention relates to portable heat radiators of the type in which the air surrounding the radiator is circulating through a radiator body or shell and heated by the flue gases from a burner combined with the radiator, and particularly to heat radiators of this type provided with means at their top to support cooking-utensils or the like to be heated by the flue gases which pass through a flue-pipe provided within the radiator body or shell.

One object of my invention is to provide a radiator of the type described which is simple and cheap in manufacture and durable in'use due to a practical construction of the radiator body.

Another object of my invention is to provide a radiator of the type described having means to permit utilization of the heat of the flue gases either substantially for cooking purposes or substantially for air heating purposes or for both said purposes simultaneously.

A further object of my invention is toprovide a radiator of the type described which is effective and economical in operation as the result of proper direction and distribution of the hot gases within the radiator body.

These and further objects of my invention will be apparent according as the following description proceeds reference being had to the accompanying drawings which form part of my invention and in which I have shown some embodiments of same by way of example.

According to Figs. 1 to 3, inclusive, and Fig. 8

the radiator comprises two end walls l0 and a shell formed by a single plate of for instance sheet iron disposed between the end walls 10 and bent so as to form the plane or substantially plane front and rear walls I2 and [4, res spectively, as well as the plane or arched-shaped top and bottom walls 15 and [6, respectively, of the radiator. The lower edges ll of the plate are separated by a transverse slot l8 extending between the end walls Ill and serving as entrance 10 for the room air into the interior 2d of the radiator. In order to strengthen the radiator and simultaneously to increase the radiating surface thereof the shell is: provided with corrugations forming outwardly extending ribs 2| separated 15 by plane portions 22. Adjacent the end walls In openings 23 are provided in the front and rear walls l2 and M as well as in the top wall I5 of the radiator.

Provided below the radiator is a burner 25 fed with liquid fuel from a fuel receptacle 26.

A flue-pipe 21 extends from burner 25 upwardly within the interior 20 of the radiator, said pipe being movable about a shaft 28 disposed adjacent the lower end thereof and mounted in bear- 25 ings 29 secured to bottom wall It. Fixed to the lower end of flue-pipe 21 below shaft 28 is a collar 30 having an external spherical or conical surface fitting tightly to a correspondingly shaped surface of a supporting member 3| fixed 30 to the bottom wall [6. The centre of the spherical surfaces or the axis of symmetry of the conical surfaces coincide with the axis of shaft 28.

Fitted into an opening in the top wall l5 of the radiator is a downwardly extending tube 35, and provided above said opening is a supporting plate 36 for cooking-utensils. Secured to the upper end of the rockable flue-pipe 2'! is a screen 31 extending to the right of said pipe as seen in Figs. 1 and 3. Fixed to the underneath side of the top wall [5 is a wedge-shaped deflector 38 comprising curved concave plates converging into a line to the left hand side of the tube 35 as seen in Figs. 1 and 3.

The flue-pipe 2'! is rockable between the end 5 positions shown in Fig. 1 by full and chain-dotted lines, respectively. In the position shown by full lines the upper end of flue-pipe 21 registers with tube 35, the flue gases from the burner 25 thereby passing exclusively to the cooking-plate 36 5o heating the cooking-utensil placed thereon. When the flue-pipe 21 is rocked into the position shown by chain-dotted lines screen 31 closes tube 35, the upper end of the flue-pipe 21 being then right below the deflector 38 which uniformly distributes the flue gases into the interior 20 of the radiator in which said gases are mixed with and give oil their heat to the room air entering through slot I8 inthe bottom wall I6 and escaping through openings 23. When the flue gases are brought into direct contact with the deflector 38 the latter is strongly heated, and in order to prevent transmission of heat from same to the top wall |5 an insulation 46 of, for instance, asbestos is provided on the underneath side of the top wall. It is to be observed that by setting the flue-pipe 21 into any intermediate position the flue gases are conducted to the cooking plate 36 as well as into the space 20. The adjustment of the flue-pipe 21 is efiected by means of a manoeuvring handle 4| connected thereto and extending through a slot 39 in the front wall |2 of the radiator (see Fig. 8).

Provided within the interior 26 of the radiator is a water tank 42 having a portion extending through the front wall I 2 and covered by a lid 43. The flue gases circulating through the radiator give off heat to the tank and heat the water content thereof, water in heated condition being drawn ofi through a cock 44.

In the modification shown in Figs. 4 and 5 the flue-pipe 21 is stationary, and intermediate adjustable' distributor being provided between the upper end of flue-pipe 21 and tube 35 in order to control the passage of the flue gases. This distributor comprises a disk 45 and a tube 46 fitted into an eccentric opening in the disk and extending downwardly therefrom, said tube 46 being rotatably'mounted on'the upper end of flue-pipe 21. In the position'of the distributor shown by full lines in Fig. 4 tube 46 registers with tube 35 so that the gases are conducted exclusively'to cooking-plate 36, whereasin the position shown by chain-dotted lines the lower end 'of tube 35 'is closed by disk 45 and tube 46is disposed right below the deflector 38' so that the'gases are 'con ducted into the interior of the radiator.

According to the modification shown in Fig. 6 the distributor comprisesa funnel '41 having an upper opening of a cross-sectional area'substantially equal to that of tube 35 and'a wider'lower opening, said funnel being movable to and-fro guided by a guiding member 48 secured to fluepipe 21 which also in this case is stationary: A horizontal screen 49 is secured to the funnel 41 approximately in level with the upper opening thereof. When the funnel 4! assumes the position shown by full lines in the figure the gases are conducted exclusively to cooking-plate 36, whereas in the position shown by chain-dotted lines the gases are conducted towards the deflec tor 38 and thence into the interior of the radiator.

It is to be observed, that in the embodiments shown in Figs. 4, 5 and 6 the rotatable'distributor" 45 and the reciprocating distributor 4'| may'also be'adjusted into'intermediate positions in'which part of the gases passes'onto the cooking-plate and the remainder onto the'deflector.

According to the embodiment shown in Fig. 7 the stationary flue-pipe 21 extends up' to the opening into the top wall l5 and carries the deflector 38. Provided in the flue-pipe 21 below the deflector are openings 5!! controlled by a damper in the form of a sleeve 5| surrounding the flue-pipe 21 and displaceable along same. A spring 52 fixed at its one end to sleeve 5| and at its other end to a bracket 53 secured to the rear wall M of the radiator tends to move the sleeve upwardly. A counter-weight 55' which may be introduced into the upper end of the fluepipe 21 rests with its lower wedge-shaped portion 56 on a horizontal rod 57 secured to the sleeve 5|. Under the action of the counterweight 55 sleeve 5| is maintained in a lowered position in which the openings 50 are open, so that the flue gases escape through said openings into the interior 20 of the radiator, the lower wedge-shaped portion 56 of the weight 55 forming thereby a continuation of the deflector 38. When weight 55 is removed, spring 52 displaces sleeve 5| upwardly into an upper position in which the openings 50 are covered, the gases passing then exclusively to cooking-plate 36.

Provided on the fuel receptacle 26 right in front of the flame of the burner 25 is a mirror 66 which is or may be placed into such an oblique position as to reflect the flame upwardly. Thereby it will be possible to control the flame without it being necessary to stoop downwardly to the level of the burner.

According to Figs. 8 to 10, inclusive, the mirror 60 is clamped to a bent portion of a stirrup 6| pivoted by pins 62 to fittings 63 fixed to the receptacle 26. Thereby the stirrup 6| may be swung inwardly into the space between the fuel receptacle 26 and the shell of the radiator (see chain-dotted lines in Fig. 9) so as to prevent damage of the mirror in packed position of the radiator or when the position thereof is to be changed. To be easily accessible the adjusting screw 64 of the wick of the burner 25 may extend between the shanks of the stirrup 6| (see According to Figs. 11 and 12 the stirrup 6| carrying the mirror 60 is removably connected with the burner, the shanks of the stirrup engaging sleeves 65 secured to the ends of a'ring 66 clamped around the lower portion of the burner housing.
